By definition, that's EXACTLY what the all star game is intended to be!
Respectfully, it's not just that. It's a lot more than that. It's intended to showcase the stars of the game. If a big star is having a down year, the people still want to see him on the field. People attending the game will want to see Soto there. I know I would, even if I wasn't a Nats fan. FOX will want Soto there. Baseball will want him there. There aren't many players that fit that bill, but he's one of them.
